To ctZZ whom it may concern.-

Be it known that we, FREDERICK A. llU- BEL and FRANK RErNiroLi), of Detroit, in the county of \Vayne and State of Michigan, have invented new and useful Improvements in Gapsule-lifold-Greasing lrlachines; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to that class of machines which are employed in the manufacture of gelatine capsules, and its specific purpose is to facilitate the lubrication of the mold pinsa step in the process of manufacturing such capsules preceding the dipping of the pins into the gelatine.

In a recent application which we have made we describe the use of the band or ribbon as a medium for transferring the lubricant to the pins, and in the present application we use the same medium, but the mode of so using it is entirely different, compelling an entirely different change in the construction of the machine, and such changes in construction are noted in this application, being principally as follows: first, the mold-pins are kept stationary while the bands are drawn tightly around them, so as to rub the pins, and there by deposit a sufficient amount of lubricant, first upon one side and then upon the other; second, the greasing-rack is easily detached and adapted to be shifted laterally; third, a combination of devices for lubrieatin the pins all around at one operation.

Figure 1 is a front elevation of our machine with the mold-plate and its standard withdrawn, showing, however, the mold-pins in their relative position, so as to illustrate the operation of the device. Fig. 2 is a horizontal section of'Fig. 1. Fig. is a rear elevation of the machine. Fig. 4is a side elevation thereof, partly in vertical section.

In the accompanying drawings, which form a part of this specification, A is the bed-plate supporting the standard B, which is adapted to be reciprocated thereon between the guides b. Rising from the rear of the bed-plate, and securely connected thereto, is the vertical bedplate G, which is provided upon its front face with a series of dovetail recesses, into which are fitted the bars D, adapted to be raised or lowered therein, and held in position, when not forcibly displaced, by the springs E, which press upon the opposite ends of each bar. This position is shown in Fig. 1, where, however, one baris shown forcibly depressed. The springs E may be provided with any of the usual devices for adjusting their tension.

F are a series of ii ngers, either round,square, 'or in roller form. as shown in the drawings. *laeli bar D carries a vertical series of such lingers projecting horizontally therefrom, and when the bars I) are not forcibly acted upon these fingers arrange themselves automatically in horizontal series, and then they correspond as to distances apart exactly with the pins of L the gelatine mold-plate G, for which the machine is designed.

F F are two additional vertical series of fingers. They are attached outside the fingers F to the vertical bed-plate (l, and are therefore stationary.

Attached to the rear face of the bed-plate G is the plate ll, into which is cut the endless groove I.

J is friction-roller attached to the opposite end of the wrist.

M is a link, one end of which is pivotally attached to the lower end of the lever K, while its other end is pivotallyattached to the bedplate 0. Each of the bars D has attached to its rear face a wrist, N, which projects through a slot, 0, in the vertical. bed-plate O, and has secured upon its end a double cam-plate, P, as shown in Figs. 3 and 4.

t is a rectangular rack, which holds in position a series of bands or ribbons, S, which are impregnated with the lubricant. Their ends are secured to clamping devices T, which in turn are secured to the rack by means of shanks c, which pass loosely through the sides of the rack, and have secured on their ends a tension device, which in the drawings consists of a coil-spring, d, and nut e. The greasingrack is kept in position upon the device by a guide, f, upon its lower side, which rests in a groove upon the bed A ,and set-screwu, which bears upon its upper side, this mode of fastening it in place allowing it to be easily shifted laterally, or removed and replaced by an other.

In practice, the parts being arranged as described, and shown in the drawings, a moldplate, G, is slipped into the standard B, as shown in Fig. 4, and then advanced so as to bring its niold pinsg between the bands S. The relative position of the pins 9, bands S, and fingers F and F is shown in Fig. 1, (except as to one vertical series of fingers, F, which is forcibly depressed.) Each horizontal series of mold-pins lies between two bands, and the fingers F are in alternating horizontal series between them and the bands. Now, the lever K, which works with its wrist in the groove I, is actuated so as to make its wrist traverse the-entire groove from one end to the other, first through its upper and then back through its lower bend. During this operation the cams P, and thereby the bars D and finger F, have been successively depressed and then successive] y raised, drawing thereby first those bands which lie on top of the mold-pins down over their upper halves, and then those below the mold-pins up and around their lower halves. As the bars D are only depressed one after another, the mold-pins are all lubricated with the same tension upon the bands, lubricating them thereby all uniformly. The fingers F serve mainly as guidepins for the bands S. In Fig. 1 one of the barsD is depressed, showing how this depression draws the top band down over the pins, rubbing (so to speak) the band over it, first one way and then rubbing it again the reverse way, owing to the action of the springs E, which bring each bar back to its original position after the lever K has moved over its cam. One oscillation of the lever will lubricate all the moldpins of one plate sufficiently for the purpose.

Different machines may easily be devised for carrying out the spirit of our invention, which simply consists in the manner of lubricating the pins by drawing the greased medium over the pins, in contradistinction from bringing it only in contact therewith, as in our former machine, where the in old-pins have to be rubbed upon the medium to deposit the lubricant properly.

What we claim as our invention is- 1. In a machine for greasing capsule molds, the combination of a mold plate, a movable support adapted to carry said moldplate, a series of greased ribbons held by elastic attachments in a frame, and mechanism adapted to force successive portions of said ribbons out of their normal planes, substantially as and for the purpose specified.

2. In a greasing-machine for gelatine-capsule-mold pins, the combination of the detachable greasing-rack, upon which the lubricating-bands are stretched, with said bands and suitable tension devices, substantially as described.

3. In a greasing-machine for gelatine-cap sulc-mold pins, the bars D, arranged to move in guides, and provided with fingers F in vertical series, in combination with devices for successively depressing the same, substantially as and for the purpose described.

4. In a greasing-machine for gelatine-capsule-mold pins, the finger-bars D, held in middle position by the springs E E, acting upon their upper and lower ends, and in combination with devices for depressing and raising the same successively for the purpose of drawing the lubricating medium over the upper and lower halves of the mold-pins, substantially as described.

5. In a greasing-machine for gelatine-capsule-mold pins, the greasing-rack provided with a series of bands with tension devices, and in combination with actuating-fingers F, arranged in horizontal series below and above each set of two ribbons, substantially as and for the purposes specified.

6. As a means for raising and lowering the finger-bars D, and in combination therewith, the grooved plateH, lever K,wrist J, and cams P. substantially as and for the purpose specified.
